Like the Greenwave Reality smart LED bulbs covered by TUAW's Mike Rose last week, the Philips Hue system can be controlled from your favorite iOS device. Not only can you turn the bulbs on and off, but as the name suggests, you can adjust the color and intensity of the light. All of that is done through a free iOS app, available now. That app even allows you to match lighting to a color from any one of the photos found in your Photo Library.

The bulbs aren't cheap -- a starter pack goes for US$199, including three LED bulbs and a special Wi-Fi controller. Additional bulbs cost $59 each. But the benefits are pretty incredible, using about 80 percent less power and having a bulb lifetime estimated at 15 years or 15,000 burning hours.

Check out the new use for your iOS device as a light-bulb controller in the video below, or visit the Philips Hue website for more information.
